Yeah only so long I could stand it too after a couple years I got out. I found it was no problem to do it and be honest to customers, but it was harder to be honest with myself and do a good job. I had to trick myself to believe the hours weren't so bad and I liked the job to keep myself in the right frame of mind to keep my energy and enthusiasm up to do really well. It wore on me after a while. It was quite an experience but I'm glad to be out.
There may be some good used buys out there, but just don't assume you're getting a good deal because its used. Compare what you could really get a new one for along with the warranty. Check out http://www.hondawarrantyinfo.com/benefits.php for your long term warranty. You can get more comprehensive coverage than just the powertrain warranty CPO cars tend to have for not all that much. Also don't assume just because its CPO that the car's top notch. You still have to take a look at things carefully. Unless you're an expert I'd take any used car to a 3rd party mechanic to get a non biased opinion.
